ABSTRACT:
An electromagnetic resonance device includes an input reflector, an output reflector, and a negative index material (NIM) disposed between the input reflector and the output reflector. The input reflector and output reflector are configured to be reflective to radiation having a wavelength of interest. The NIM is configured to have a negative refraction at the wavelength of interest. A first radiation is reflected by the input reflector toward the first surface of the NIM, passes through the NIM, and is focused on the output reflector as a second radiation. The second radiation is reflected by the output reflector toward the second surface of the NIM, passes through the NIM, and is focused on the input reflector as the first radiation. A gain medium may be included to amplify the first radiation and the second radiation to generate a laser radiation.
